SELF-GAUGING FLEXIBLE SHIN'GLE.

Application filed August 10, 1923. Serial No. 656,644.

To all whom it may concern:

' Be it'known that I, ALBERT Annn Gms- WoLn,-a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in self Gauging Flexible Shingles, of which the following is a specification.

My invention has reference to an improvement in shingles and more particularly to an improvement in flexible shingles as shown in United States Patent No. 1,274,410, granted to me August 6, 1918, for flexible shingle. In. the heretofore usual construction of shingled roofs on which flexible shingles are laid diagonally, gauge lines are used for spacing or gauging the shingles in laying the shingles. These gauge lines are usuall of cord or string; they are secured. at @2101 end to the roof and require skilled labor in accurately placing the gauge lines on the roof. The use of these auge lines also adds materially to the cost 0% shingling a roof.

The object of my invention is to improve the construction of flexible shingles adapted to be laid diagonally, whereby each flexible shingle is provided with a shingle laying gauge, thereby eliminating the use and cost of gauge lines heretofore used for this purose.

p A further object of my invention is to construct such a flexible s ingle with a shingle laying gauge, so that t ere is no waste or additional cost in forming the gauge part of the shingle.

Another object of myinvention is to reduce the cost of shinglin a roof with flexible shingles laid cliagona 1y.

My invention consists in the peculiar and novel construction of a flexible shingle adapted to be laid diagonally, said flexible shingle having a shing e laying gauge and details of construction, as Wlll be more fully set forth hereinafter and claimed.

Figure 1 is a plan view of a portion ofa flexible-shingled roof, each of said flexible gauge for accurately laying the shingles.

Figure 2is a face plan view of my improved self gauging flexible shingle.

Figure 3 is an inverted plan viewof my improved self gau ing flexible shingle, and lfiigure 4 is an e ge view of the self-gaugin" shingle.

I raised gauge edges 16 and 17, at

T the drawing olindicatesthe l slieathing of a roof and 6, 6 my improved self gauging flexible shingles. The roof sheathing 5 may also represent the sheathing on the outer walls of a building.

The flexible shingles '6, 6 are constructed as shown in my previous patent referred to, of a flexible material and each have abent under lower corner flap 7 with a transverse fastening wire 8 having outwardly extendlng side ends 9, 9, as shown in igure 3, which go under the angular lower shingle edges 10, 10, as shown in Figure 1, of shingles previously -laid,to hold down the lower end of the shingle. The shingle is square in form and has a fiat back 11, a flat face 12, preferably of ground slate, straight lower angular edges 10, 10, straight upper angular edges 13, 13 and side corners 14, 14:, as shown in Figures 2. and 3.

In constructing my improved flexible shingle and shingle layin gauge, I fold over the upper end corner 0 the shingle and form the same into a raised overlying gauge flap 15, which lies flat on the face 12 of the shingle and is preferably the same size and shape as the lower fastening flap 7. This raised overturned gauge flap 15 with its straight I right angles to each other, forms the shingle laying gauge of the shingle.

In layin and fastening the shingles each course'of shingles is laid, secured and nailed as described in my previous patent referred y the use of my improved shingle with its sh ngle laying gauge, each next upper course of shingles is laid by placing each shingle so that the adjacent upper angular edgel3, of a shingle on the left will come against the gauge edge 16 and the adjacent upper angular edge 13 of a shingle on the on the overlying gauge flap 15, the corners 14, 14 of the left and right shingles touchright, will come against the gauge edge 17,

ing each other and also touching the corner of the overlying gauge flap 15, as shown in, Figure 1. This is repeated in layin the' course of shingles anglin layin each to low-' ing; course of shingles, the s ingle laying gauges bringing each shingle into its correct position on the roofand the angular lines formed by the angularedges 10, 10 and 13, 13 of the shingles are thus made straight and true, when the'shin'gling of the roof i Q0113 "'pleted. I a

- his, conetructiony th 1}i 1ig1 ,r1 i gfI gauge is'forin'ed integral with the shingle, without waste of material. and without increased eost of manufacturing the shingle.

Having thus described my invention I 6 claim as new 2-- 1. A shingle adapted to he laid diagonally and having an upper overturned corner flap, said overturned corner flap lying tinton the face of the shingle and forming a shingle 10 laying gauge, for the purpose as described.

2. A shingle adapted to be laid diagonally and having an upper turned over corner flap, said turned over corner fiaplying flat on the ace of the shingle and having straight raised gauge edges at. right angles 15 to each other, all formed integral, for the purpose as described.

In testimony whereof, I have signed my name to this specification.

ALBERT ABBE GRISWOLD.
